Soy candles are a great way to express yourself creatively and can be customised with different colours and scents. When making soy candles, it is important to know when to add the fragrance oil to the melted wax. The general rule is to add the fragrance oil when the wax has cooled slightly, usually at around 155°-165° F for soy wax, but this may vary depending on the type of wax and fragrance oil being used. It is also crucial to use the correct amount of fragrance oil, as too much oil can cause the fragrance to separate from the wax, creating an uneven burn and a potential fire hazard. Stirring the mixture for several minutes after adding the fragrance oil ensures that it binds properly with the wax, resulting in a stronger scent.

What You'll Learn
The ratio of fragrance oil impacts the success of your candle
The ratio of fragrance oil added to soy candles is crucial to their success. While it may be tempting to add more fragrance oil to create a stronger scent, this can lead to complications such as a weak scent throw or even a potential fire hazard. The key is to find the right balance, as too much fragrance oil can cause the oil to separate from the wax, resulting in unsightly "gooey" spots and a clogged wick.
To calculate the correct amount of fragrance oil, you can use either the Fragrance Load or Fragrance Content method. The Fragrance Load method involves measuring the percentage of oil relative to the wax, while the Fragrance Content method calculates the percentage of oil relative to the combined weight of wax and oil. For example, if you have 200g of wax and want a 10% scent load, you would need 20g of oil using the Fragrance Load method and 22g of oil using the Fragrance Content method.
It's important to note that the type of wax and fragrance oil used will also impact the ratio. For instance, soy wax typically requires a higher ratio of fragrance oil compared to other types of wax. Additionally, the potency of the fragrance oil must be considered, as a stronger fragrance may require a lower percentage.
When adding fragrance oil to soy wax, it is crucial to ensure that the wax temperature is below the flashpoint of the fragrance, which is typically between 50-55 degrees Celsius. Adding the fragrance oil at the proper temperature will help it bind to the wax, resulting in a stronger scent throw. Stirring the mixture for several minutes is also important, as stirring for too short a time can cause the oil to settle at the bottom of the wax and weaken the scent throw.
By following these guidelines and carefully measuring the ratio of fragrance oil, you can ensure the success of your soy candles and create a high-quality product with a strong and pleasant scent.

The type of oil used will determine the percentage added
When making candles, the type of oil and wax used will determine the percentage of fragrance oil added. For instance, when using All Seasons Wax, a fragrance load of 6% to 8% is recommended to ensure a good scent throw without impacting the flame's ability to burn through the viscous fragrance oil. However, some candle makers have reported using up to 10% fragrance oil with soy wax. It's important to note that adding too much fragrance oil can cause the oil to separate from the wax, creating "ugly gooey spots" and potentially becoming a fire hazard.
The quality of the fragrance oil also plays a role in determining the percentage added. High-quality and concentrated fragrance oils, such as those from Luxury Candle Supplies, have a suggested usage of only 6% to 8%. Additionally, the potency of the fragrance oil will impact the percentage used.
Candle makers use different units of measurement for fragrance oil, such as ounces or millilitres, but it's crucial to stick to one unit to ensure the correct percentage is added. The fragrance load is calculated based on the volume of the jar and the desired percentage of fragrance oil.
Another factor to consider is the temperature at which the fragrance oil is added to the wax. The ideal temperature range for soy wax is 180-185°F (between 50-55°C), as this helps the fragrance bind to the wax and prevents the oil from becoming volatile and catching fire.
It's worth noting that candles with a high soy content tend to "sweat," releasing excess oil during temperature changes or when exposed to warm environments. Therefore, it's recommended to slightly reduce the fragrance load in warmer months.
Overall, finding the right percentage of fragrance oil to add requires experimentation and testing. Makers should start with low percentages and gradually adjust until they achieve the desired scent throw without compromising the quality and safety of the candle.

Soy wax typically melts at 130° F
Soy wax is a popular choice for candle-making due to its renewability, biodegradability, and cleaner burn compared to other types of wax, such as paraffin wax. It also has a longer burn time, making it a cost-effective and sustainable option. Soy wax typically melts at 130° F (54.4° C), which is lower than the melting point of paraffin wax. This lower melting point means that soy wax candles will begin to melt and release their fragrance at a lower temperature than candles made from other types of wax.
When making soy candles, it is important to add the fragrance oil at the right temperature to ensure optimal fragrance binding and release. The ideal temperature range for adding fragrance oil to soy wax is between 175° F and 185° F (79° C and 85° C). Adding the fragrance oil within this temperature range helps to ensure that the oil binds properly with the wax and reduces the risk of the fragrance evaporating.
However, it is important to note that the flash point of the fragrance oil, which is the temperature at which it becomes volatile and may catch fire, should also be considered. The flash point can vary depending on the specific fragrance oil being used. Therefore, it is crucial to refer to the instructions or product information for the recommended temperature range for adding fragrance oil to soy wax.
Additionally, the amount of fragrance oil added can significantly impact the success of your soy candle. Using too much fragrance oil can lead to issues such as candle "sweating," where excess oil is released during temperature changes or when the candles are exposed to high temperatures. It can also affect the quality of the burn and create "gooey" spots on the candle. Thus, it is important to follow the recommended usage percentage for the specific fragrance oil being used and start with low percentages to avoid these issues.
Overall, by paying attention to the melting point of soy wax, adding fragrance oil at the appropriate temperature, and using the correct amount of fragrance oil, you can create soy candles with a strong and pleasant fragrance that burns efficiently and safely.

The fragrance load is affected by the pour temperature
The fragrance load of a candle is the amount of fragrance oil added to the wax. The pour temperature can affect the fragrance load in several ways. Firstly, the fragrance load is dependent on the type of wax being used. Different types of wax have different melting points, and the fragrance oil needs to be added at a certain temperature relative to the melting point. For example, the melting point of soy wax is around 118-125°F, and it is recommended to add the fragrance oil at around 135-140°F, which is 10-15°F higher than the melting point.
Secondly, the pour temperature can affect the strength of the fragrance. If the wax is too hot when the fragrance oil is added, a lot of the fragrance can be lost before the candle sets. On the other hand, if the wax is too cold, the oils may not blend well, resulting in a weaker scent. Therefore, it is important to find the right balance by adding the fragrance oil within the recommended temperature range for the specific type of wax.
Thirdly, the pour temperature can affect the appearance of the candle. If the wax is poured at a higher temperature, it can result in more shrinkage as it cools, leaving a smoother product with better adhesion. However, pouring at a lower temperature can also improve the appearance by reducing the risk of cracks or other imperfections.
Additionally, the pour temperature can impact the safety of the candle. If the wax is too hot when the fragrance oil is added, it can increase the risk of the oil separating from the wax, creating "gooey" spots and potentially becoming a fire hazard. Therefore, it is crucial to follow the recommended temperature guidelines for the specific type of wax and fragrance oil being used.
Lastly, the pour temperature can also affect the curing time of the candle. Curing is the process of allowing the candle to sit and fully develop its scent after it has hardened. If the fragrance oil is added at a lower temperature, it may take longer for the candle to cure and for the scent to fully develop.
